Buy a pair if you have rolled an ankle before, if you train barefoot on a hard floor, or if you are getting through high-volume kicking sessions. If none of those apply, treat them as a comfort item rather than a necessity.
Muay Thai ankle supports are among the cheapest things in a kit bag and easily the least understood. Most people assume they stop you rolling an ankle. They're actually not great at preventing this. The evidence on what actually prevents ankle injuries is more specific than the marketing around this category suggests.
Why do Muay Thai fighters wear ankle supports?
They protect you from your own footwork rather than from your opponent. Muay Thai pivots on the ball of the foot — every round kick, every switch, every turn of the hip — and almost always barefoot. An elastic anklet keeps the joint warm, applies light compression and protects the skin from friction against the canvas.
That last point is key. Muay Thai is one of few sports trained barefoot for hours at a time, and the skin on your feet and ankles takes a beating that has nothing to do with getting hit.
A study of 123 Muay Thai practitioners across nine gyms in northern Thailand examined feet and ankles directly rather than relying on self-reporting. It found callosity in 59% of them, tight heel cords in 57% and open wounds in 10%, and attributed the pattern to prolonged barefoot training. An anklet will not fix a tight calf, but it does put a layer between your skin and the floor.
What the research actually says
There is good evidence that external ankle supports prevent re-injury. A systematic review of inversion ankle sprains found bracing cut sprain risk by around 69% and taping by around 71% — but only among athletes who had already sprained that ankle. For preventing a first sprain in someone with no history, the same review found no comparable support.
Two things follow from that, and both are worth knowing before you spend anything.
First, that research is about tape and rigid or semi-rigid braces. It is not about elastic cotton anklets. A Thai anklet is a compression garment. It does not mechanically restrict the joint the way a braced or taped ankle does, so it would be dishonest to attach those numbers to it.
Second, a common claim about this whole category does not hold up. Pooled evidence from a meta-analysis found that taping and bracing produce no measurable improvement in proprioception — your sense of where the joint is in space — among people with recurrent sprains or instability. If a product is sold to you primarily on improving proprioception, treat that carefully.
What the evidence does establish is why the first sprain matters so much. Roughly a quarter of active people develop chronic ankle instability, and among those who have sprained an ankle before, that figure rises to around 46%. Once you have rolled one, it is genuinely more likely to happen again — which is exactly the group the bracing and taping evidence supports.
What an anklet does, and what it does not
Realistic expectations make this an easy purchase.
What it does:
- Keeps the joint warm, and a warm joint is harder to injure than a cold one
- Applies light compression, which most people find helps a slightly grumbly ankle get through a session
- Protects skin from friction burns against canvas and mats
- Absorbs sweat, and keeps the ankle covered on a shared training floor
What it does not do:
- Stop a hard roll. Nothing made of cotton will
- Replace tape or a proper brace if you have diagnosed instability
- Fix the underlying weakness — that takes balance and strength work
Do you actually need a pair?
Buy them if you have rolled an ankle before, train on a hard floor rather than mats, do high-volume kicking or long pad rounds, or are coming back from an injury and want the joint warm and supported.
You can comfortably skip them if you train a couple of times a week on mats, have never had an ankle problem, and are not doing heavy kicking volume. They are useful rather than essential, and anyone telling a brand-new beginner they are mandatory is selling something.
If you are working out what to buy first, our essential Muay Thai equipment for beginners guide puts this in order — gloves, wraps and shin guards come well before anklets.
Anklet, tape or brace?
Pick based on whether you have an injury history, not on price.
An anklet suits everyday training for most people. It is comfortable, quick to put on, and does the warmth and skin-protection job well.
Tape suits a known problem ankle on a specific day, and the evidence behind it is strong. The catch is that it needs applying properly every session, and it causes more skin irritation than fabric supports do.
A semi-rigid brace is the option with the most evidence behind it for someone with recurrent sprains, but it is bulkier and restricts the ankle in ways that interfere with pivoting. If you have rolled the same ankle repeatedly, that is a conversation to have with a physiotherapist rather than a shopping decision. Our guide to the most common Muay Thai injuries covers what to watch for.
Getting the fit right
Snug, not tight. An anklet should stay where you put it through a full round without you thinking about it.
If your foot goes cold or starts to tingle, it is too small — take it off. Compression that cuts circulation is worse than no compression at all.
Anything that slides down your foot mid-round is doing nothing except annoying you. That is nearly always a sizing problem rather than a fault in the product, so spend the extra thirty seconds choosing a size rather than defaulting to whatever loads first.
One useful trick: an anklet worn on the calf takes up slack in a shin guard that is slightly too large. Our shin guard size guide covers that in the sizing section.
What we stock
Frankly, what we stock is all very similar and there isn't much between brands besides colours. Every pair of Muay Thai ankle supports we carry is elastic fabric, hand made in Thailand and sold in pairs. Anyone claiming a dramatic difference between Thai anklets is overselling.
Fairtex
The most common and well established. Elasticated, with reinforced edging specifically to stop fraying, which is where cheap supports fail first. Sold as a pair, with a wide range of colours.
Twins Special
About as common as Fairtex and near enough the same product. Elasticated, reinforced edges, and pitched by Twins on comfort and freedom of movement rather than lockdown, which is a fair description of how they feel.
The weakness is availability rather than design.
MTG Pro AS2
The same job, with two small practical touches: a size tab on the rear so you can tell a pair apart in a cluttered kit bag, and a range built for juniors as well as adults. Elastic cotton and breathable.
Looking after them
Wash them. Regularly.
These are worn barefoot against a shared training floor, and that study of Thai gyms found open wounds on one practitioner in ten. Fabric that sits between broken skin and a mat needs washing after every few sessions, not at the end of the month.
Cool wash, air dry, never on a radiator. Buy two pairs if you train most days, so one is always clean and dry. They cost little enough that this is a sensible thing to do.
Frequently asked questions
Do ankle supports prevent rolled ankles?
Not in the way people assume. Elastic anklets provide warmth and compression rather than mechanical restraint, so they will not stop a hard roll. The strong evidence for preventing recurrent sprains applies to tape and semi-rigid braces, and mainly in people who have already injured that ankle.
Should beginners wear ankle supports?
They are useful rather than essential. Gloves, hand wraps and shin guards all come first for a beginner. If you are training barefoot on a hard floor, or you have rolled an ankle in another sport, a pair is worth having from the start.
What size ankle supports do I need?
Check the size options on the product listing rather than guessing from your shoe size. Then judge it on the floor: it should sit snug and stay put through a full round. If your foot goes cold or starts to tingle, the support is too small, whatever the label says.
Are ankle supports the same as ankle guards?
Yes, the terms are used interchangeably in Muay Thai. Both describe the elasticated compression anklet worn during training. They are different from a medical ankle brace, which uses rigid or semi-rigid components to physically restrict how far the joint can move.
How often should you wash ankle supports?
Every few sessions at minimum. They are worn barefoot against shared mats and canvas, absorb a lot of sweat, and sit against skin that is often broken from training. Cool wash and air dry — heat degrades the elastic and shortens their life considerably.
Which pair should you buy?
Fairtex or Twins, in your size and a colour you like. That is what we would hand you across the counter, and the reinforced edging on both outlasts cheaper anklets. Choose the MTG Pro AS2 instead if you want a junior pair, or you like the idea of a size tab on the rear. Primo once they are back.
A history of rolled ankles: buy the anklet for daily training, but talk to a physiotherapist about tape or a brace for hard sessions. The research is clear that this is the group external support helps most, and equally clear that a cotton anklet is not what was tested.
